The Atlanta Falcons don't open training camp until Thursday, but linebacker Lofa Tatupu has already been added to the walking wounded.

"Lofa sustained a pectoral injury while working out recently (Thursday)," coach Mike Smithtold the team's official site. "At this point, we do not know the extent of the injury, but we expect to have more information early next week."

Tatupu missed all of 2011 after a pair of knee surgeries, but said he could have played. After he wasn't picked up by anyone, Tatupu considered retirement, according to The Boston Globe. He spent his first six seasons with the Seattle Seahawks, who drafted him in the second round in 2005.

The Falcons have promised an update, so we'll keep on top of this one.
